2011年，编程语言使用排行榜

from： http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html

Creating software applications for mobile devices is hot. Think of the recent rise of Objective-C because of the iPhone and iPad we have seen. But now also scripting language Lua is getting more and more popular. The major advantages of Lua are its small footprint and fast performance. A year ago, Apple decided to allow Lua to run on iOS systems. Nowadays many popular iPhone apps have been written in Lua, including Angry Birds.

Traditional web scripting languages, on the other hand, have a hard time. They are quickly losing market share at the moment. Take a look at the decline of PHP, but also Ruby and Python are going down.

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, Bing, Yahoo!, Wikipedia, YouTube and Baidu are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here
